# Create and manage AWS Transit Gateway Flow Logs using APIs or the CLI
Create and manage Flow Logs using the APIs or CLI

You can perform the tasks described on this page using the command line.

The following limitations apply when using the [create-flow-logs](https://docs.aws.amazon.com/cli/latest/reference/ec2/create-flow-logs.html) command:
+ `--resource-ids` has a maximum constraint of 25 `TransitGateway` or `TransitGatewayAttachment` resource types. 
+ `--traffic-type` is not a required field by default. An error is returned if you provide this for transit gateway resource types. This limit applies only to transit gateway resource types.
+ `--max-aggregation-interval` has a default value of `60`, and is the only accepted value for transit gateway resource types. An error is returned if you try to pass any other value. This limit applies only to transit gateway resource types. 
+ `--resource-type` supports two new resource types, `TransitGateway` and `TransitGatewayAttachment`.
+ `--log-format` includes all log fields for transit gateway resource types if you do not set which fields you want to include. This applies only to transit gateway resource types.
